Hard to say.
I had the Best gasket in when the crank chewed it up, but that was due to the out of round seal groove. It was so tight it actually burned the crank and I had to polish it before reinstalling.
When I re-did it I used the two piece BOP seal, worked as advertised. When I had to build it again after the lifter failure, I tried a one piece BOP but I couldn't get it installed correctly so I used a two piece.

Dave, over at SD Performance, recommends the one piece but says it takes two guys to install it. The one piece seal makes more sense and I would use that as long as I had someone to help me lay the crank.

I'll attach a photograph of the crank seal surface before I polished it. I don't think it would have mattered what seal was in there, it was going to leak with the seal groove that far out of round.
